The Mexican long-nosed bat roosts in Big Bend National Park in West Texas. The bat feeds on nectar and pollen and hovers while it feeds. Additionally, its tongue can extend up to eight centimeters. The features of Mexican long-nosed bats are evidence of natural selection because the features are adaptations that — lead to an increase in predation by other species of animals lead to an increase in predation by other species of animals show that most DNA mutations are necessary and advantageous but do not increase survival or reproductive success show that most DNA mutations are necessary and advantageous but do not increase survival or reproductive success help individuals outcompete other individuals for food resources to increase survival and reproductive success help individuals outcompete other individuals for food resources to increase survival and reproductive success are the result of intentional breeding
Natural selection results in adaptation, increasing in the individual's fitness. Option C. Features are adaptations that help individuals outcompete other individuals for food resources to increase survival and reproductive success.
What is natural selection?
Natural selection is an evolutive force.
It selects beneficial alleles in a population and increases their frequency.
It is the result of the phenotype-environment interaction which determines gene destiny in space and time.
Natural selection results in adaptation, meaning that it causes an increase in the aptitude phenotype.
Aptitude (or fitness) is reflected by the phenotype that results in the survival, fertility, and capability of having a mate. It is a way of measuring the individual ability to leave fertile offspring.
In many cases adaptations, resulting from natural selection can be correlated to environmental factors or selective pressures applied by other organisms or habitats.
In the exposed example, the features are adaptations that help individuals outcompete other individuals for food resources to increase survival and reproductive success.
selective pressure ⇒ competition for resources
influence in fitness ⇒ increase survival and reproductive success.

How does carbon enter the biotic components of the carbon cycle?
A) through the process of respiration
B)through the process of photosynthesis
C)through the combustion of fossil fuels
D) through decomposition of dead organisms
In the carbon cycle, plants take CO2 from the atmosphere and carry out photosynthesis by which they incorporate carbon into the biotic components of organic compounds.
What is the carbon cycle?It is a biogeochemical cycle that starts with carbon dioxide in the atmosphere, which is adsorbed together with the sun's energy in the photosynthesis process of plants.
Characteristics of the carbon cycleDuring the day, plants use the Sun's energy to convert CO2 from the atmosphere plus water into carbohydrates and oxygen, this process is photosynthesis.Therefore, we can conclude that the carbon cycle is a cycle that flows through the terrestrial ecosystem, through the photosynthesis of plants, by animals or decomposing organisms, and the oceans.

carbon dioxide consumption
water consumption
oxygen consumption
sugar consumption
Carbon dioxide consumption
Carbon dioxide consumption can be used to measure primary productivity in an ecosystem.
Primary productivity refers to the rate at which energy is converted to organic material by photosynthesis.Primary productivity can be calculated by analyzing the change in biomass of producer organisms.Primary productivity can also be calculated by analyzing the movement of carbon dioxide (consumption).
Primary productivity can also be estimated by analyzing the movement of carbon dioxide the movement of oxygen over time.
In conclusion, carbon dioxide consumption can be used to measure primary productivity in an ecosystem.

The bending of dynamic equilibrium receptors is caused by the gelatinous cap called the . 6. The bending of static equilibrium receptors is caused by tiny stones called
Receptors placed in the different areas of the vestibular apparatus detect the types of equilibriums. 1) crista ampullaris, 2) utricle and saccule, 3) maculae, 4) semicircular canals, 5) cupula, 6) otoliths.
How is the vestibular apparatus composed?Three main areas compose the vestibular apparatus. These are the
utricle, saccule, and semicircular canals. What are the different types of equilibriums?The vestibular apparatus detects two types of equilibriums,
• The static equilibrium → Head and body position relative to gravity
• The dynamic equilibrium → Head and body position relative to rotational acceleration and deceleration.
These types of equilibriums are detected by receptors placed in different areas of the vestibular apparatus.
• Static equilibrium receptors are located in the macula of the utricle and saccule. They help to maintain balance.
• Dynamic equilibrium receptors are located in the semicircular canals. They provide information about the rotational movement.
The sensory hairs are located in the crista of the ampulla, at the base of each canal (crista ampullaris).
The sensory hairs are covered by a dense gelatinous material named cupula, the otolithic membrane.
The otoliths are calcium carbonate crystals placed over the cupula. Their movements depend on the head’s movements.
